A new technique for targeting stem cells towards sites of cardiovascular injury has been developed at UCL. This technique would increase the regeneration of the damaged tissues. The technique involves targeting endothelial progenitor cells have been magnetically tagged with an iron containing agent. The progenitor cells can then be directed towards the damaged arterial cells using an externally positioned magnet.
It was found that following this magnetic technique there was a five-fold increase in cell localisation to the damaged vascular tissue observed in rats. This technique uses and already FDA approved material used currently in MRI imaging. This means the technique could be in clinical trials within 3-5 years. – CT
